The song "I Used to Love H.E.R." from Resurrection ignited a feud with West Coast rap group Westside Connection. The lyrics of the song criticized the path hip-hop music was taking and was interpreted by some as directing blame towards the popularity of West Coast Gangsta rap. Westside Connection first responded with the 1995 song Westside Slaughterhouse, with the lyrics "Used to love H.E.R. mad cause I fucked her". Westside Connection recorded tracks venting their issues with rival East Coast rappers (see East Coast-West Coast hip hop rivalry). Westside Slaughterhouse also mentioned Common by name, prompting the rapper to respond with the scathing Pete Rock-produced attack song "The Bitch in Yoo". Common and Westside Connection continued to insult each other back and forth before finally meeting with Louis Farrakhan and setting aside their dispute. Following the popularity of Resurrection, Common Sense was sued by a Orange County-based reggae band with the same name, and was forced to shorten his moniker to simply Common.
